Abstract

The present invention provides a method for measuring a location. The method comprises: receiving, by a User Equipment (UE) and from a serving cell, information on a bandwidth allocated for a positioning reference signal (PRS); receiving, by the User Equipment (UE) and from at least one or more neighbor cells, information on a bandwidth allocated for a PRS; determining whether there is a difference between the bandwidths; and measuring, by the UE and based on a result of the determination a timing difference between PRSs transmitted from the serving cell and the at least one or more neighbor cells.
